STUD.

To @ZZ 'whom t may concern Be it known that I, JAMES E. BRADY, a citizen of the United States, residing in New York city, county of New York, borough of Manhattan, and State of New York, have invented certain new and useful Improvements in Studs, of which the following is a full, clear, and exact specication.

My invention relates to building studs and refers particularly to studs useful in the construction of partitions.

Partitions, composed of plaster, cement or similar materials, may be classified into solid partitions and hollow partitions, and the stud of my invention is suitable in the construction of both of these forms of partitions.

The object of my device is a cheap, light, eliicient partition stud, readily applied to partition construction with a minimum amount of time and labor.

In the production of partitions of the character described, it has been previously customary to erect a series'of vertical studs of wood or metal which were fastened to vthe floor joist and ceiling joist by means of nails or bolts. To these studs were nailed, or otherwise fastened, a series of lath, plaster-board or other foundation material as a base for the' nal'layer of plaster or cement.

The production of partitions in the manner described hasmany difculties and objectionable features. The large amount of wood has a tendency to make the partition non-lireproof, metal studs are expensive and heavy, a very considerable amount of labor is required to position the studs and the remainder of the base elements and continual plumbing is necessary to insure a properly aligned structure.

Hollow tiles, or bricks, have been employed for the production of hollow partitions, but these have the objection of high cost, the necessity of a great amount of labor incident to their proper laying and the ditliculty incident to the proper alignment of the partition surface or face.

My device overcomes all of these objections and diiiiculties and presents a means whereby fire-proof partitions of either solid or hollow formation may be effectively constructed with a minimum of weight, time and labor.

I have found that a stud of double con- Speccation of Letters Patent. Pagmtgd Aug', 15, 1922, Applicationmed July so, i

cavo-convex formation possesses valuable advantages not found in other forms of studs, in that it possesses sufficient strength and stability even if made of heavy cardboard.

I have further found that a stud of this formation possesses other' advantages in that it allows of the speedy production of partitions which, on account of the uniform ybody of cement, plaster or other material employed, is fire-proof, the plaster, or other material, forming a unified body of re-re sistant material and of great stability irrespective of the stud.

Among the other advantages of my device is its adaptability to the production of both solid and hollow partitions, whether produced from wood lath, metal lath, fabric, plaster-board or any other materials capable of being used for this purpose.

The device of my invention comprises two connected concavo-convex bodies attached to each other with their concave faces exposed outwardly. l

In the accompanying drawings 'and de` scription thereof, I refer to a paper stud, but I do not limit myself to this particular substance, paper being mentioned in order to show that even this cheap, light material may be usedk to produce a firm, permanent lire-proof partition, and that my device requires a minimum of time in that the production of a partition therewith eliminates all the labor incident to nailing, screwing or bolting together the various members.

In the accompanying drawings, illustrating modifications ofthe device of my invention, similar parts are designated by similar numerals. v

Figure 7 is partly a horizontal section and partly a top plan view showing my device in the construction of a solid partition, employing a fabric.

Figure 8 is a broken side elevation of Figgure 7, with the plasterremoved."

`Figure 9 is a broken horizontal section of cave faces carry a series of extended guide` members12, 12, for purposes to be described later, aad the members 10, 10 have a` series ofholes, or openings 18, 13. The members 10, 1() carry ani extended foot, or support, 14, preferable of wire screening, a similar support, not shown, being` carriedby the upper entremitiesof the members 10, 10.

Figures 1, 2, 3,4@ andu illustrate the use ofuny device in the production of al partitionwith `the use of plaster-board, the means of employment being as follows A series of the connected concave-,convex members 10, 10 are placed in spaced position i withtheir concaverfaces toward each other. and are maintained in position by fixing the supports 111, letto the floor and ceiling joist by means of plaster or cement.` The connected concave-convex members are so spacedy fromeach` other thatlplaster-board may be situatedwbetween them` and maintained in position by rneansfof` the guides 12, 12. A coating of plaster is placedupon the` concave faces of the studs andza plaster-board 15 is placedbetween the guides y12, 12 of the adjacent studs.` A spacing clip `16` is then placed around each member ofthe studs and another plaster-board inserted, the `clip 16 `spacing the two plaster-boards from each other. This process is` followed until a plaster-board partition is formed supported by theistudsa Plaster 17 is now placed over the entire structure, including the plasterboards and the studs. During this plastering operation, thezplaster goes through the holes `18, 13 of thestuds and between the spacesbetweenthe plaster-boards, thus forming al concrete unified structure of plaster, in which the studs are imbedded, the whole being of such a formation as `to form a fireproof partition.

Figure 6 discloses a` method of making hollow lire-proof partitions by means ofthe device of my invention.` In this `particular form'ofconstruction, the studs are erected in the manner described above and carry the two plaster-boardsl, 15 which are spacedly necting and binding means.

in Figure 10, the. two members 10,` 10 are connected with each other by the concrete, or plaster, members 18, 18, through which a wire 19 passes and is turnedover upon the outer faces of the plaster-boards as a conrlhe series of Plaster-boards are separated from each other by thel spacing clips 16, 1G, as described above, and the entire structure covered with plaster to form the partition.

VFigures 7 and-8 illustrate a method of 75 producing a solid partition ,by means of my device' employinora textile fabric as open;-` worlr burlap. n f this modification, the properlength of fabric 20, vnecessary for the production ofthe partition, is fastened between a series of the concavo-conveX members at proper distances `fromeach other by means of clip 21 whichbinds together the burlap and the two elements 10, 10. It is to be noted that in this form of construction the concave faces of the stud face outwardly. Plaster `17 is then` placed over the entire. structure, forming a solidiire-proof` partition.

Figure 9 illustrates a method of producing a hollow partition by means of my d e-f vice employing a fabric. In this modification the fabric 2O is attached at intervals to a series of studs, a' layer of fabricibeing 'so attached tothe concave face of each member` 95 10 of. thestud. The entire `structure is then covered with plaster, forming ahollow fireproof partition.

ln thexmodification of my device, showny connected together, but spaced from each other by` meansfof. the cement, or plaster, member 22, `through which :the wire 23 passes and is turnedoverthe concave face. ofeach ymember 10, as a holdingandbinding member; Each stud carries a seriesof2 suchmembersr22,l rlhe objectfofzthis modilication is tov allow,y of the formation ofa thicker partition thanl could be formed `if the members `10, 10 abutted upon each other.

The utility, strength, effectiveness,l novelty, ease of erection and economy of cost ofmy device are illustrated by the foregoing description of it and its several methodsy of use. l i 1 f y I do not limit myself toY the exact size, shape, number, material or arrangement of parts as shown and described, all of which maybe varied without going beyond thek scopey ofmy invention as shown, described 12o and claimed." y
